Sealing structure and sealing method

Abstract

The invention discloses a sealing structure which comprises a first component to be sealed, a second component to be sealed and a sealing strip arranged between the first component to be sealed and the second component to be sealed. The first component to be sealed or the second component to be sealed is provided with a groove, and lap joint portions at the two ends of the sealing strip are arranged in the groove. The sealing structure has the beneficial effects that the groove is formed in the inner side of the component to be sealed, the sealing strip achieves connection in a lap joint mode, the lap joint portions are arranged in the groove, the sealing effect of the small-thickness sealing strip in the sealing process can be achieved, operation steps are simplified, and meanwhile the good sealing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a sealing structure and a sealing method. Background technique [0002] For the annular structure that needs to be sealed, the sealing ring is often selected for sealing. For the complete sealing ring, the manufacturing process of the complete sealing ring is troublesome, the cost will be high, and there will be a lot of waste of raw materials. In order to improve this situation, it is installed with a long strip of sealing strip, that is, by cutting the long strip of sealing strip to an appropriate length, and then connecting the two ends, installing it to the place where the sealing structure is required for sealing, which This connection scheme is usually connected in two ways: one is to install the sealing strip along the place to be sealed, and the two ends of the sealing strip directly touch together. Due to the poor control of the installation between the two end faces to...

Problems solved by technology

[0003] In the prior art, such as Chinese patent application numbers 200620029094.6, 201210155549.9, and 201320243995.5, all disclose how to strengthen the sealing structure of the seal, but in the technical solutions of the above patents, they are all made at the connecting end of the sealing strip so as to be easy to splice In order to increase its contact area and achieve a good sealing effect, but for the sealing strip with small thickness, the processing of the structure at the end will increase the workload, and the sealing strip is usually stored in rolls. Temporary cutting will also cause rough treatment, affect the sealing effect, and fail to achieve the standardized quality of similar products. Therefore, it is necessary to design a new sealing structure to solve this problem.
